The revolutionary James Webb Space Telescope and next-gen radio telescopes are probing what’s known as the epoch of reionization. It holds clues to the first stars and galaxies, and perhaps the nature of dark matter.
When the Sun doesn’t shine and the wind doesn’t blow, humanity still needs power. Researchers are designing new technologies, from reinvented batteries to compressed air and spinning wheels, to keep energy in reserve for the lean times.
This record-setting year for heat saw stunning auroras, a map of a brain, a Dengue epidemic, the first look at rocks from the far side of the Moon, an AI energy scramble and more
Neurologists have grappled with a cluster of amyotrophic lateral sclerosis cases in France, where a fondness for a toxic wild mushroom may hold the answer
Miles away from the ocean, projects are afoot to clean up salty groundwater and use it to grow crops. Some say it’s a costly pipe dream, others say it’s part of the future.
Hint: It involves finding just the right proteins. With new ingredients and processes, the next generation of substitutes will be not just more egg-like, but potentially more nutritious.
VIDEO: Knowable Magazine’s interviews with experts during the pandemic revealed many missed opportunities and blunders in the US response to Covid-19, which was marked by excess American deaths and disability. The experience does offer lessons on how to better prepare for what scientists call the inevitable emergence of the next global health emergency.
VIDEO: Tens of millions of people are living with long Covid. Yale immunologist Akiko Iwasaki explains the current state of play in the search for causes of, and treatments for, this potentially debilitating illness.
VIDEO: Even a mild SARS-CoV-2 infection can cause inflammation that disrupts neural communication, says Stanford neurologist Michelle Monje. Her concern is that Covid-19 may leave millions dealing with cognitive problems, from a loss of mental sharpness to lapses in memory, that prevent them from returning to their previous level of function.
VIDEO: Where do new diseases come from? As people increasingly push into remote areas, the risk of encountering new pathogens increases, says wildlife epidemiologist Jonna Mazet.
VIDEO: In August 2020, the Dome Fire burned more than 40,000 acres of the iconic species’ range in the Mojave Desert, leaving a graveyard of blackened trees. A massive replanting effort now underway hopes to return life to the fragile ecosystem by boosting numbers of the climate-threatened plant.
VIDEO: Delays, errors and a fragmented response initially kept public health officials in the dark about the spread of SARS-CoV-2. More tests and easy access could still play a critical role in slowing the virus.
VIDEO: New York Times science reporter Apoorva Mandavilli chronicles the rise of the delta variant, the latest of many twists in the pandemic that she’s covered since it began. Delta has left parents in an especially tough spot, with schools opening but young children still vulnerable.
VIDEO: The pandemic has highlighted the complex links between inequality, racism and disease risk in America. Harvard public health scholar David Williams explains.
VIDEO: Scientists expected the novel coronavirus would mutate and change. But its runaway spread means new, more dangerous variants are more likely to emerge. Harvard computational geneticist Pardis Sabeti explains.
Scientists are seeing signs of resistance to the infections that have been wiping out the world’s amphibian populations — and developing strategies to aid in the fight Down Under
COMIC: Using tools from fields like fluid dynamics to better understand how groups of people move around can improve flow and make large gatherings safer
Kids with disruptive mood dysregulation disorder have explosive outbursts well past toddler age. Scientists are trying to work out the causes and what treatments help.
Unusual variations in the cellular protein factory can skew development, help cancer spread and more. But ribosome variety may also play biological roles, scientists say.
One class of drugs has already found success in treating the painful, disorienting and common attacks. Excitement is building about a slew of additional drug targets.
Population and animal studies suggested it could treat cancer, but the clinical trials were a bust. Here’s what happened and what potential may remain.
Cuckoos, cowbirds and other species outsource their parental duties. Scientists are uncovering new twists in this sneaky — and often treacherous — game of survival.
To understand the origins of multicelled life, researchers are studying a motley assortment of simpler animal relatives. The commonalities they’re unearthing offer a trove of clues about our mutual past.
